  1. 11. Chitosan and chitosan/wheat gluten blends : properties of extrudates, solid films and bio-foams

    Author : Fei Chen; Mikael Hedenqvist; Eliane Espuche; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents four different studis describing the characteristics and processing opportunities of two widely available biopolymers: chitosan and wheat gluten. The interest in these materials is mainly because they are bio-based and obtained as co- or by-products in the fuel and food sectorIn the first study, high solids content chitosan samples (60 wt.

  2. 12. Symbolic Supervisory Control of Resource Allocation Systems

    Author : Zhennan Fei; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Allocation System; Binary Decision Diagram.; Discrete Event System; Supervisory Control Theory;

    Abstract : Supervisory control theory (SCT) is a formal model-based methodology for verification and synthesis of supervisors for discrete event systems (DES). The main goal is to guarantee that the closed-loop system fulfills given specifications. SCT has great promise to assist engineers with the generation of reliable control functions. READ MORE

  3. 13. English teaching in China : EFL teacher motivation and demotivation at the university level

    Author : Fei Liu; Andrea C. Schalley; Solveig Granath; Maria Kuteeva; Karlstads universitet; []
    Keywords : HUMANIORA; HUMANITIES; EFL teachers; higher education; career motivation; motivation; demotivation; level of motivation; lexical richness; syntactic complexity; English writing proficiency; English; Engelska;

    Abstract : Teacher motivation has been shown to be a major factor that affects students’ motivation to learn a second language; however, English as a foreign language (EFL) teachers’ motivation has not been given enough attention, particularly in the Chinese context where English plays a key role. Thus, this study investigates the motivation of English teachers at the university level in China in order to prepare the ground for the development of recommendations on how to enhance teacher motivation and thereby improve teaching quality and student performance.

  4. 14. Hand-held Augmented Reality for Facility Maintenance

    Author : Fei Liu; Stefan Seipel; Julia Åhlén; Ewert Bengtsson; Xiangyu Wang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Augmented reality; Façade; Image registration; Thermal infrared imaging; Facility management; Third person perspective; Target designation; Precision study; Experiment; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Buildings and public infrastructures are crucial to our societies in that they provide habitations, workplaces, commodities and services indispensible to our daily life. As vital parts of facility management, operations and maintenance (O&M) ensure a facility to continuously function as intended, which take up the longest time in a facility’s life cycle and demand great expense.

  5. 15. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling

    Author : Fei Peng; Junliang Sun; Xiaodong Zou; Dag Nores; Ute Kolb; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; rotation electron diffraction; structure determination; cooling; Inorganic Chemistry; oorganisk kemi;

    Abstract : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. READ MORE
